Abstract: A jet pump comprising a jet nozzle for accelerating a propellant. The jet nozzle has a convergent inlet part and an outlet part connected to the convergent inlet part. The outlet comprises an inner wall diverging at an opening angle. The opening angle is designed such that a propellant flowing through the outlet part at subsonic speed is detached from the inner wall and a propellant flowing through the outlet part at supersonic speed is guided by the inner wall. An automatic, cost-effective and simple changeover of the jet pump to different pressure ratios is hence provided.

Abstract: A vehicle drive having a vacuum system for a vehicle having an internal combustion engine that is connected to a supply air line and to an exhaust air line. The vacuum system has an ejector. A propellant gas line opens into a nozzle channel of a propellant nozzle of the ejector. The nozzle channel opens into a mixing chamber of the ejector through a nozzle opening. A suction line opens into the mixing chamber and the mixing chamber on an outlet side opens directly or indirectly into a mixed gas line. The mixed gas line opens into the supply air line. The suction line is connected to a vacuum consumer, and the nozzle opening in the propellant nozzle is formed by a nozzle edge having teeth and/or corrugations.

Abstract: The present invention relates to a nozzle appliance for a jet pump, comprising a driving nozzle and a first suction nozzle, wherein the first suction nozzle is arranged radially outward of the driving nozzle and wherein the nozzle appliance is designed such that a fluid flow through the driving nozzle drives a fluid flow through the first suction nozzle. The invention also relates to a jet pump comprising a corresponding nozzle appliance.

Abstract: A device for connecting two tubular objects has a connection piece housing and a securing element. The securing element is shaped in a complementary manner with respect to a receiving opening of the connection piece housing and is arranged rotatably in the receiving opening and has an insertion opening for receiving a connection piece. The securing element has securing tabs which are spaced apart from one another in the circumferential direction and each have a radially inwardly facing securing body for engaging in shaped features of a connection piece and can be moved from a first position into a second radial position lying radially on the outside. The connection piece housing has, for each securing tab, a ramp surface which is bevelled radially inwards and on which the securing tab rests.

Abstract: A clamp for fastening an object in the form of a tube or hose, having an elongate clamp strap at each of the ends of which there is provided a radially outwardly projecting fastening leg, and having a rubber profile which is provided on the radial inner face of the clamp strap and which at least partially engages around each of the edges of the clamp strap by way of a lip. At least one first holding geometry is provided on the radial inner face of the clamp strap, and at least one second holding geometry is provided on the radial outer face of the rubber profile.

Abstract: A device for degassing a liquid flowing in a liquid line is provided. The device has an inlet opening, an outlet opening, and a capillary element having an inner wall surface. The capillary element extends between the inlet opening and the outlet opening. The inlet opening is connected in a fluid-communicating manner to the outlet opening and is connected in a fluid-communicating manner to the liquid line. The inner wall surface has a material that is liquid-repellent for a liquid flowing in the liquid line. A device is thus provided for degassing a liquid flowing in a liquid line that reduces the time needed for degassing.

Abstract: A fluid line having a wave form portion is furnished. The wave form portion extends at least at a minimum distance along a longitudinal axis of the fluid line. The wave form portion has a wave peak element (18), which itself has, along a peripheral direction extending around the longitudinal axis of the fluid line, a varying distance from the longitudinal axis, the distance including a distance curve in the peripheral direction, the distance curve providing a non-circular contour. A fluid line is thus provided having a wave form portion, which fluid line reduces the pressure drop at the wave form portion.

Abstract: A clamp for fastening an object in the form of a tube or hose, having an elongate clamp strap at each of the ends of which there is provided a radially outwardly projecting fastening leg, and having a rubber profile which is provided on the radial inner face of the clamp strap and which at least partially engages around each of the edges of the clamp strap by way of a lip. At least one first holding geometry is provided on the radial inner face of the clamp strap, and at least one second holding geometry is provided on the radial outer face of the rubber profile.

Abstract: An angle piece for fluidically connecting fluid lines of a vehicle. The angle piece has a channel portion for altering a flow direction of a fluid about an alteration angle. An input flow direction of the fluid into the angle piece and an outlet flow direction of the fluid from the angle piece form limbs of the alteration angle. At least one guide element is arranged in the channel portion, which guide element protrudes into the channel portion. The at least one guide element altering the flow direction of a part of the fluid by the alteration angle. The angle piece thus has a low pressure drop.

At least one first holding geometry is provided on the radial inner face of the clamp strap, and at least one second holding geometry is provided on the radial outer face of the rubber profile.

Abstract: A clip has a clip strap which has a first edge and a second edge and a clamping device for clamping the clip strap. The clip strap has recesses which are arranged between the first edge and the second edge and are spaced apart. The clamping device has a guide channel designed so as to complement the clip strap, for guiding through the clip strap. The clamping device has at least one first sprung detent tongue having a first free end, which protrudes into the guide channel and is oriented obliquely with respect to a clamping direction of the clip strap predefined by the guide channel in such a way that when the clip strap is guided through the guide channel in the clamping direction, the first free end latches successively into recesses of the clip strap.
